New Analytical Boundary Condition for Optimized Outphasing PA Design

A novel analytical approach is used to determine a new boundary condition for optimal operation of a class B Chireix outphasing PA. In the proposed method, a threshold outphasing angle is defined as a new design parameter and used to optimize the power stage in an outphasing system.
